[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In order to solve the above problems, the present invention provides a waterproof connection component for a rotatable rolling shutter blade 1. Figures 1 to 4 , including a plurality of blades 1 and a waterproof sealing strip 2; the blade 1 is provided with a first rotating part 3, a second rotating part 4, a first sealing groove 5 and a second sealing groove 6; the first rotating part 3 and the second rotating part 4 are arranged on both sides of the blade 1 relatively, and adjacent blades 1 are connected in a flippable manner through the first rotating part 3 and the second rotating part 4; the first sealing groove 5 and the second sealing groove 6 are arranged on both sides of the blade 1 relatively, and the first sealing groove 5 and the second sealing groove 6 are arranged on the flipped outer side of the blade 1; the waterproof sealing strip 2 is elastically clamped between the first sealing groove 5 and the second sealing groove 6 between adjacent blades 1, and the waterproof sealing strip 2 seals the gap between adjacent blades 1. When in use, adjacent blades 1 are folded, rotated and rolled up through the first rotating part 3 and the second rotating part 4, and the waterproof sealing strip 2 can seal the gap between adjacent blades 1, such as Figure 2 As shown in the figure, when the rolling shutter blade 1 is laid flat, the waterproof sealing strip 2 is squeezed and deformed to play a sealing and waterproof role; Figure 1 As shown, when the rolling shutter blade 1 rotates, the inner side of the waterproof sealing strip 2 is compressed, and the outer side is stretched and deformed to play a sealing and waterproof role.

[0025] After adopting this setting method, the waterproof sealing strip 2 can seal the gaps between the rotating parts of adjacent blades 1 and the rotating parts of adjacent blades 1, that is, the gaps between adjacent blades 1 are elastically sealed by the waterproof sealing strip 2 to prevent water from flowing out of the gaps between adjacent blades 1, completely solving the problem that the existing rotatable roller shutter blades 1 cannot be waterproof.

[0026] Regarding the above-mentioned rotating part, Figure 1 and Figure 4 As shown, the first rotating part 3 is an arc-shaped piece 30, and the convex arc of the arc-shaped piece 30 faces the adjacent blade 1; the second rotating part 4 is a crescent-shaped groove 40, the slot axis of the crescent-shaped groove 40 is the same as the length direction of the side wall of the blade 1, and the notch of the crescent-shaped groove 40 faces the adjacent blade 1; the arc-shaped piece 30 matches the shape of the crescent-shaped groove 40, and the arc-shaped piece 30 can be slidably installed in the crescent-shaped groove 40. After adopting this setting method, when the blade 1 is laid flat, the arc-shaped piece 30 is completely arranged in the crescent-shaped groove 40. When the blade 1 is folded, the arc-shaped piece 30 will slide from the crescent-shaped groove 40, thereby realizing the folding rotation between adjacent blades 1.

[0027] For the arc-shaped sheet 30, if Figure 1 and Figure 4As shown, the arc-shaped piece 30 includes a straight segment 31 and a semicircular segment 32; the straight segment 31 is used to form a first sealing groove 5 with the first sealing convex wall 50, and the semicircular segment 32 is arranged at the notch of the first sealing groove 5. After adopting this arrangement, the arc-shaped piece 30 can form a rotating part that cooperates with the crescent-shaped groove 40.

[0028] For the crescent-shaped groove 40, if Figure 1 and Figure 4 As shown, the second rotating part 4 includes an arc-shaped wall 41 and a bar 42. The arc-shaped wall 41 is arranged along the length direction of the side wall of the blade 1. The length direction of the bar 42 is the same as the length direction of the arc-shaped wall 41. The bar 42 is arranged in the space enclosed by the arc-shaped wall 41. The bar 42 is fixedly connected to the side wall of the arc-shaped wall 41 to form a crescent-shaped groove 40. After adopting this arrangement, the arc-shaped wall 41 can form a crescent-shaped groove 40 with the bar 42 to achieve the limitation of the rotation stroke.

[0029] Regarding the first sealing groove 5, as Figure 1 and Figure 4 As shown, the blade 1 is provided with a first sealing convex wall 50, and the first sealing convex wall 50 is provided on the end surface of the flipped outer side of the blade 1, and the first sealing convex wall 50 is arranged on the side of the blade 1 where the arc-shaped piece 30 is provided; a first sealing groove 5 is formed between the arc-shaped piece 30 and the first sealing convex wall 50. After adopting this setting method, the formed first sealing groove 5 can elastically clamp the waterproof sealing strip 2 together with the second sealing groove 6.

[0030] Regarding the above-mentioned second sealing groove 6, as Figure 1 and Figure 4 As shown, the blade 1 is provided with a second sealing convex wall 60, and the second sealing convex wall 60 is arranged on the end surface of the flip outer side of the blade 1, and the second sealing convex wall 60 is arranged on the side of the blade 1 where the second rotating part 4 is provided; a second sealing groove 6 is formed between the second sealing convex wall 60 and the adjacent first rotating part 3. After adopting this setting method, the formed second sealing groove 6 can elastically clamp the waterproof sealing strip 2 together with the first sealing groove 5.

[0031] Regarding the above-mentioned waterproof sealing strip 2, as Figures 1 to 4 As shown, the waterproof sealing strip 2 is provided with a matching groove 20, the length direction of the matching groove 20 is the same as the length direction of the waterproof sealing strip 2, the matching groove 20 matches the shape of the arc-shaped piece 30, and the arc-shaped piece 30 is installed in abutment with the matching groove 20. After adopting this setting method, when the rolling shutter blade 1 is laid flat, the matching groove 20 squeezes the waterproof sealing strip 2 to deform and play a sealing and waterproof role; when the rolling shutter blade 1 rotates, the matching groove 20 also applies pressure to the inner side of the waterproof sealing strip 2, and the outer side is stretched and deformed to play a sealing and waterproof role.

[0032] It should be pointed out that the sealing strip is made of a plastically deformable rubber material.

[0033] Regarding the above-mentioned blade 1, Figure 3 As shown, the flipped inner side surface of the blade 1 is an inner bending surface. After adopting this arrangement, the blades 1 are connected by arc surfaces, and adjacent blades 1 can be rotated by a certain angle along the center of the arc.

[0034] Specifically, Figure 3 As shown, the flip inner side surface includes a first plane section 10, a first inclined surface section 11, a second plane section 12, a second inclined surface section 13 and a third plane section 14; along the direction from the first rotating part 3 to the second rotating part 4, the first plane section 10, the first inclined surface section 11, the second plane section 12, the second inclined surface section 13 and the third plane section 14 are sequentially connected by surface transition, and the surface of the first inclined surface section 11 is arranged opposite to the surface of the second inclined surface section 13. After adopting this setting method, the arc-shaped flip inner side surface can make the blade 1 fit in an arc shape after flipping.

[0035] It should be noted that the blade 1 is generally formed by extrusion of aluminum alloy, which is light in weight and high in strength.

[0036] The basic structure and principle of this solution can be known from the above, and will be explained below with practical applications.

[0037] The utility model provides a rolling curtain device, which applies the waterproof connection component of the rotatable rolling curtain blade 1 of the first technical solution.

[0038] Rolling shutter devices include but are not limited to rolling shutter doors, rolling shutter windows, and rolling shutter sheds. After adopting this setting method, rolling shutter devices that use waterproof components connected to rotatable rolling shutter blades 1 can achieve waterproofing and prevent water from flowing in through the gaps in the blades 1.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
